Longer explanation: the supposed paradox of tolerance is when people whine about not being protected by tolerant society when they do something intolerant. They claim society isn’t so tolerant if it doesn’t tolerate their intolerance.

In reality, society is built upon social contracts. One of those contracts is tolerance. If someone is intolerant, they’ve broken the social contract and therefore are no longer protected by that contract. In fact, it is society’s responsibility to reject the intolerant actors to protect the rest of society.
